specification-of- Letters Patent:

Patented J n'e 1, 1915.

Application iled Maya, 1911.. Serilalo.- 824,837.

To'all whom it may concern Be it known that I, GEoRGE-.H. GILLE'i'rE,

a citizen of the United States,and resident of the lborough of Manhattan, city, county,

its distance from the guard and for securely` retaining the blade-in operative position, the; featuresof: construct-ion and arrange# ment whereby this object is attained being hereinafter described in detail and. specified in theI claims.

In theI drawings Figure- 1, is-a back. view\ of one form' of embodimentbf the improvements; Fig. 2, is a plan view thereof, and Fig. 3, a side view of the- Same. Fig.- 4, is aside viewof another form of embodiment; Fig. 5, is a section on theline 5, 5,- of Fig. 4, and a plan of the parts belowthat line. Fig. 6, is an enlargedside view partly in section, but showing the adjusting device in full, the form being the vsame as in Figs.'-

4, and 5.

In Figs. 1, 2, and 3, of these drawings a, represents the handle, which is shown corrugated or fluted in a well known Way, but its exterior surface may be plain, or it may be made with any style of configurations which pleases the fancy. The small end b, of the handle a, is joined or secured by solder or otherwise to the middle of the base c, of the holder, which, as shown, has its front edge formed into a guard or guardteeth al, the extreme front ends e, e', being wider than the teeth for the purpose of receiving the sharp edge corners of the blade and protecting the face against cutting. The back f, of the holder, is bent up at an angle to the base on which the handle' is joined, and this back part f, also has a bend or angle g, which forms a rest for the/back of the blade. As shown the same piece of metal has an opening in it above and in front of the blade rest g. The opening is surrounded bythe back and by end pieces h, h, and a front piece or clamp i, the end andsfrolbtpeoes being bent and curved over in such a Way as to form a spring and clamp on. thefblade-j, near itsr cutting edge and oven-ftheguard teeth.' The back of theblade j, .is-shownlas having a U-shapedstiffener cfsuch-as commonly belongs to or forms a part of bladesof the style shown. The stiil'e'ner lc,- seats in the angle rest g, and the end pieces h., 11.press on the: front of the stifener so as-to keep the/bladeA back in the rest, while the front part or clamp z', presses the? 'blade f down near the cutting edge.' Thuin-the blade is kept tirmin its place and firm at its edge, Theaback f, of the holder isf-provided `with a collar or stud l, secured thereto by solder or otherwise, and a threadedA opening4 is made through thiststud and the backf, for receiving a screw m,. havingits outer end terminating inf-a collar or s tud ln, joined to a milled head 0,'.for permittingit to be turned by thumb andlinger. The threads. on the screw terminate near its inner or free end which is-beveled or rounded and bears against the under side of the blade '7',`So as to press the blade up against the -clamp z', which will yieldaslthelblade Yis pressed` away from the guardv teeth 'or raised bv the screw.

In thev form of embodiment shown by Figs. 4, y5, Aand (i, the structure is essentially the same as to the handlefa, its small end l), holdersbase c, guard-teeth d, corner supports e, e, back f, bend or blade rest g, end pieces h, clamp z', of the spring, blade j, and the blade stilener c. In this form of embodiment, however, the handle a, has a milled head o', at its larger or outer end, and an inside collar or stud l', from which a shaft m', extends on the inside of the handle to and through the holder c, and the shaft m', also has an oval shaped shank or pin which after passing through a wedge or cam fn, is headed or secured like a rivet. In this instance the milled head o', may be turned by thumb and finger so as t'o rotate the shaft m', and also the cam or wedge n', which is thereby made to act on the under side of the blade,`the latter pressing against the spring as the cutting edge is raised from the guard teeth. g

In the structure shown by all figures, the adjustment or the raising and lowering of' the cutting edge `is positive and sure, and can be made to a nice degree according to the requirements of the user as to closeness of shave. The rotary movement of the screw or shaft, may be the smallest part of a turn, or several full turns may be made in the screw adjustment, or a half turn made in the wedge or cam adjustment, the extreme lift with the latter being shown on an exaggerated scale by the enlarged View of Fig. 6.

The improvement admits of considerable modification or variation in the details of the precise means used for producing a rising pressure on the blade, and a like blade pressure on the retaining spring. The form of the holder and spring may also be modified, that shown being intended to illustrate a cheap form of guard, holder, and spring made of a single piece of metal. The integrally formed holder, guard and spring, has some special utilities, but the adjusting devices may also be used with other spring retained blades.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A safety razor comprising a thin blade provided at its rear edge with a sti'ening piece, a handle, and a blade holding head having a base portion rigidly secured to one end of the handle and provided at its front l edge with a guard, a rear portion extending upwardly behind the rear edge of the blade and provided with a shoulder forming a seat for the same, and a spring portion extending forwardly over said stiliening piece and thence downwardly into position to engage the front portion of the blade and press its cutting edge toward the guard, said spring portion being shaped to make contact with the front edge of the stiii'ening piece and thereby prevent forward movement of the blade.

2. A safety razor comprising a thin blade provided at its rear 'edge with a stiifening piece, a handle, and a blade-holding head having a base portion rigidly secured to one end of the handle and provided at its front edge with a guard, a rear portion extending upwardly behind the rear edge of the blade and provided with a shoulder forming a seat for the same, and a spring portion extending forwardly over said stifening piece and thence downwardly into position to engage the front portion of the blade and press its cutting edge toward the guard, said spring portion being shaped to make contact with the front edge of the stifi'ening piece and thereby prevent forward movement of the blade, and means for lifting the cutting edge of the blade from the guard to adjust the distance between them.

3. In a safety razor, a handle member and a blade holder, the said blade holder being rigidly mounted on said handle, a blade mounted in said holder, a guard, and means carried by the handle member for directly engaging the blade intermediate its ends to adjust the cutting edge in a direction away from the guard, said means comprising a rotatable stem mounted in said handle and a head carried by said stem, said head being formed Awith a cam surface which upon rotation of the stem varies the distance of the cutting edge of the blade from the guard by the pressure of the head against the blade.
